Description

витс  и медленно раствор етс , местами исчеза  совсем с поверхности образца. На образцах , покрытых припоем с серебром, пикакого вли ни  среды не обнаружено.whites and slowly dissolves, in places disappears completely from the surface of the sample. On samples coated with silver and solder, no effect of the medium was found.

Электрохимические исследовани  показали, что в сульфатном растворе припой с серебром и сталь Х18Н10Т имеют одинаковые стационарные потенциалы (-0,7 в), тогда как потенциал припо  без серебра равен 0,9 в (относительно хлорсеребр ного электрода сравнени ).Electrochemical studies have shown that in a sulphate solution, solder with silver and X18H10T steel have the same stationary potentials (-0.7 V), whereas the potential of solder without silver is 0.9 V (relative to the chlorine-silver reference electrode).

При испытании в серной кислоте оба припо  дали одинаковые показатели.When tested in sulfuric acid, both solders gave the same performance.

Введение в припой серебра благопри тно вли ет на его смачиваемость, вследствие чего компенсируетс  некоторое ухудшение последней , св занное с уменьшением содержани  никел .The introduction of silver into the solder has a favorable effect on its wettability, as a result of which some deterioration of the latter, which is associated with a decrease in the nickel content, is compensated for.

Механические свойства нового припо  не отличаютс  от механических свойств ранее за вленного припо .The mechanical properties of the new solder are not different from the mechanical properties of the previously claimed solder.
